Osama Krayem (Arabic: أسامة كريم, born 16 August 1992), also known as Naïm or Naim al Hamed,[1] is a Swedish-Syrian convicted terrorist and mass murderer.

[9][10] Krayem is thought to have radicalized in his early twenties, frequently watching videos by Anwar al-Awlaki, an American and Yemeni imam and Islamic lecturer and alleged senior recruiter and motivator involved in planning terrorist operations for the Islamist militant group Al-Qaeda.

[13] The Wall Street Journal reported that on 20 April 2016 that Belgian authorities spelled the subject's first name as "Ossama," where previously it had been publicised as "Osama."

In January 2015, he was identified by the Swedish press yet again in a Facebook post sent to his brother in Sweden showing him reportedly in Deir ez-Zor, Syria dressed in military fatigues, standing in front of an ISIS flag and holding an AK-47.

At trials it was also disclosed that Krayem and Tunisian Sofien Ayari also both were involved in planning a separate attack on Amsterdam airport as part of the same cell.

[12] During interrogation, Krayem confessed that he was the second metro bomber[24] also carrying a backpack full of explosives, and explained that he felt regret at the last moment and therefore never tried to detonate his suicide bomb.

[25] During trial in 2018, Belgian investigators found that Krayem was at the scene where 26-year-old Jordanian air force pilot Moaz al Kasasbeh was burned to death by ISIL in January 2015.
